APPENDIX C 



ADDITIONS TO THE COLLECTION OF APPARATUS. 



SINCE the death of Dr. Daubeny many additions have been Collec- 

 made to the collections of instruments belonging to the tlons * 

 Laboratory, additions rendered necessary by the ever-varying 

 requirements of instruction and examination, as also by the 

 continual development of science, and in some cases special 

 apparatus have been acquired which was necessary for 

 particular research work carried out in the Laboratory. A 

 few specimens have also been added to the collections. 



The chief acquisitions of apparatus, taken in chronological 

 order, are : 



1867. Meteorological and Physical Instruments. 



1869. Wrought-iron Digester tested to stand a steam 

 pressure of 500 Ib. to the square inch. (Presented to the 

 Laboratory by Mr. Chapman.) 



1872. Series of Anatomical Preparations in illustration of 

 Professor Rolleston's Forms of Animal Life, which was 

 prepared by Mr. Charles Robertson, formerly Demonstrator 

 to the Linacre Professor. The preparation of the exoskeleton 

 of the Lobster, which has been added to this series, was made 

 by Mr. Chapman. 



1874-6. Apparatus for Physiological Experiments. 



Among the instruments purchased was an excellent 

 Thomson's Reflecting Galvanometer by Elliott, which has 

 been of the greatest use to us, and which has also been 

 borrowed by Professor Gotch for use at the Museum ; also 

 a first-rate Long Beam Balance by Oertling, the possession 

 of which enabled Mr. Armitage to perform his very accurate 

 redetermination of the Atomic Weight of Boron. 



1892. Physical Apparatus necessary for the performance 

 of certain elementary physical experiments, a practical 

 acquaintance with which had been required by the Board
